runnerattachments for baby buggies.

An object-of th invention is to provide an improvedsledrunnenattachment for a baby buggy.

Another'objectof' the invention is to provide an improved. sled, runner attachment for baby buggies which will'be collapsiblewhen the wheels 11f. theubaby buggy are. to engage the ground, and will be extensible to elevate the wheelsabove the ground-when the runners are to contact the groundin the event that it is covered with snow.

Afurt-her object of theinvention is to provide an improved-sled runner attachment for baby buggies including a substantially rectangular frame adapted tO'ibG clampedto -th front and rear axles'ofababybuggy; with dependin longitudinally extending sled runners linked thereto for movement toward and. away from said frame, and a pivoted actuating yoke mounted upon the rear links formed with latches on the forward ends thereof adapted. to be selectively engaged and locked in position in adjusting notches in the rear upper edges of said side frame members i and 2.

A still further object of the invention is to provide an improved sled runner attachment for baby buggies which will be highly efficient in operation, and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application,

In carrying out the invention. there is provided an illlDI'OVBd'SlGd, runner attachment for baby buggies comprising a, substantially, rectangular shaped supporting frame including. transversely spaced longitudinally. extending. side frame members i and 2,,and.,a, pair ofinlerted U;- sh'aped cross. frame members; 3,.and. 4. con: nected between said. side frame members inwardly of their opposite ends.

The front and. rear axles 5.. and .'6, .of. aebaby buggy '3 support the front and rear wheels 8 and 9., respectively, of. said bu gy, nd sa d. ax es are placed in position to overlie; thecross frame members 3 and 4 and to be secured theret'o by means of the hooked fasteners i3 extendingabout said axles and through the cross frame members 3 and i. The lower ends of the fasteners 55 are threaded to receive the securing nuts H for holding the same in clamped or secured position about said axles 5 and 6.

A plurality of spaced openings l2 will be formed'through the side frame members I and 2 adjacent their front ends for varying the position of the front cross frame member 3 for accommodating the device to baby buggies having different frame sizes or wheel bases.

The inverted U-shaped supporting link members l3 and M are pivotally connected to the front and rear ends of the side frame members i and 2, and are formed with the diagonal braces l5 and i5 welded or otherwise secured between the sides and base portions of said supporting link members.

A pair of longitudinally extending angle iron sled runners H and i8 are bent upwardly slightly at their front ends, and are attached to the depending lower ends of the supporting link members. The rear ends of therunners I1 and I8 are bent upwardly at right angles, and are connected together by means of the cross member or bar I9.

A U-shaped actuating yoke 2!! is provided with side arms 2| and 22 pivotally supported upon the rear depending supporting link members M, at 23 and 24, and the forward and upper ends of said side arms 2| and 22 are formed arcuate in shape extending upwardly and outwardly of said side frame members I and 2. Inwardly and downwardly extending latch pins 25 and 26 are fixed to se ed. in the notch 21 i rmedin th upper r ar edges of said side frame members I and 2 when said attachment and frame is in extended position and the baby buggy wheels 8 and 9 are in contact with the ground.

Coil springs 29 and 30 Will be connected at their forward, lower ends to the sled runners I! and I8, and have their rear upper ends attached to the arcuate portions of the yoke arms 21 and 22 for resiliently holding the latch pins 25 and 26 in the notches 21 and 28.

Assuming that the sled runners I1 and I8 are in contact with the ground, and the wheels 8 and 9 are elevated above the ground. If a bare spot on the ground is encountered, pressure will be applied upon the actuating yoke 25 within convenient reach of the foot of the operator, causing the runners to swing upwardly, allowing the wheels 8 and 9 to engage the ground. When it becomes necessary to use the runners l1 and 18, a foot is braced against the rear runner connecting bar I9 and the buggy I is pulled back by the handle 3| until the latch pins 25 upon the yoke arms 2| and 22 lock in the notches 2! in the side frame members I and 2.

From the foregoing description, it will be apparent that there has been devised and provided a highly efficient form of sled runner attachment for baby buggies.

While the preferred embodiment of the instant invention has been illustrated and described, it

will be understood that it is not intended to limit invention, what is brace bars on said frame, fastening means adjustably carried by said bars for securing the frame to the axles, a front and rear pair of vertical supporting members pivotally carried by said brace bars, runners pivotally secured to the lower ends of said supporting members, locking bars pivotally secured to the rear pair supporting members, angular locking pins disposed on the inner surfaces of one of each of the ends of the locking bars and slidably disposed on the upper edges of the brace bars, locking recesses formed in the upper edges of said brace bars for accommodating said pins to lock the runners in a raised. and lowered position, means for releasing said pins from the recesses including a transverse foot bar disposed between the locking bars, resilient means connected between said locking bars and the runners for normally urging said runners upwardly and a transverse foot bar disposed between the runners for moving the same downwardly and moving the frame portion carrying the recesses into engagement with the locking pins.
